I plugged in WD A to the Laptop, and when the menu popped up, it indicated that I had plugged in WD B.* I wondered how I could have mixed them up, but I stopped it, unplugged it, and plugged in the other drive.* When the menu opened, it indicated that it was also WD B.* I opened the folders on the HD and all the appropriate files were there.* I stopped the drive, unplugged it, and plugged the first drive back in to the Laptop's USB port.

The window that opened once again indicated that this drive was WD B and that it contained the four file folders that are supposed to be on WD B, but when I tried to open the folders, they were empty.* I went back to the menu of My Computer, and moused-over the drive name.* It indicated that the drive had 400 GB of data, which is correct for WD A, but I can't access any of the data.* The folder named A does not appear.

So external hard drive WD A has taken on the name and the folders of external hard drive WD B.* It does not appear to have any of the actual files from WD B, and WD A appears to have the correct amount of data on it, but the folder containing that data has disappeared.

It's sort of a Twilight Zone moment.

I don't recall actually transferring any data between the two drives.* I have not previously had any problems with the two drives.* Both drives are less than a year old, and I purchased them new.* I usually stop and remove any external drives before I put the computer into hibernate mode.

I plugged the problem drive into a different computer, running Windows XP, to see if the name change and missing data problem were still there, and the problem was exactly the same.

Can anyone help me out here?* I would like to get my files back.* Thanks.
